A distillation unit for producing potable water using solar radiation is disclosed. The distillation unit includes a heating chamber defining an interior chamber adapted to contain a non-potable liquid for distillation, and a dome-shaped condensing portion having an inner surface and an outer surface, with the condensing portion disposed over the heating chamber such that the heating chamber and the inner surface of the condensing portion are provided in fluid-transfer communication. The distillation unit also includes a pre-heat jacket having a first surface and a second surface and an interior defined therebetween adapted to receive non-potable liquid for distillation therein. The first surface is disposed adjacent the outer surface of the condensing portion, and the pre-heat jacket defines an access entry for introducing non-potable liquid for distillation into the interior of the heating chamber. The distillation unit also includes a trough adjacent for receiving a potable liquid therein.

An evaporation still for producing sea salt having a chamber that contains a bottom, a plurality of sides including a front side, a back side, a first side, and a second side, the front side and the back side being substantially parallel, and the first side and the second size being substantially parallel, and a top. The top contains a centered portion extending from the first side to the second side, the centered portion being substantially parallel to the front side and the back side, a first window extending in a downward slope from the centered portion towards the front side, and a second window extending in a downward slope from the centered portion towards the back side. The evaporation still also contains a plurality of legs. The first window extends from the centered portion beyond the front side such that condensation formed inside of the chamber drains outside of the chamber, and the second window extends from the centered portion beyond the back side such that condensation formed inside of the chamber drains outside of the chamber.

The present invention is a laboratory condenser adapted to be interchangeable from functioning as a reflux condenser to functioning as a distillation condenser as by inversion, and related methods of reflux and distillation that may be carried out by its use.

The present invention is a process for producing various types of cannabis extract from harvested cannabis. A quantity of harvested cannabis, which typically includes the inflorescence, floral leaves, and small stems of a flowering cannabis plants, is pre-frozen and is first subjected to cryogenic grinding to produce pulverized cannabis. The pulverized cannabis is then subjected to butane extraction at a low temperature to produce an initial cannabis extract. The butane in the initial cannabis extract is removed by evaporating it from the mixture in a cold vacuum chamber. The process preserves desirable waxes and lipids and removes the butane from the extract without subjecting the extract to heating in order to preserve the integrity of the terpenoids and flavonoids in the extract.

A dehydration device removes moisture from a process gas compressed by a compressor, and includes a contactor that causes a dehydration solvent to absorb the moisture, a still column that separates the moisture from the dehydration solvent, a carrying line that carries the dehydration solvent from the contactor to the still column, a dehydration solvent conveying pump, a bypass line that couples the carrying lines upstream and downstream of the dehydration solvent conveying pump, a first on-off valve disposed in the bypass line, and a control device. In a case where the pressure detected by a pressure sensor is lower than a first predetermined pressure, the control device closes the first on-off valve and causes the conveying pump to operate, whereas in a case where the pressure detected by the pressure sensor is equal to or higher than the first predetermined pressure, the control device opens the first on-off valve and causes the conveying pump to stop.

Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an alkanolamine and converting the carbon disulfide to a higher boiling point product, thereby reducing or eliminating carbon disulfide from the product stream. Subsequent removal of the higher boiling point product via distillation can lead to a purified sulfide stream with high purity.
